I have a Little Giant Still Air Incubator. This is my 2nd hatch, and it appears to be a disaster.
I am hatching French Black Copper Maran and RIR eggs. Prior to my first hatch, I was warned about keeping the humidity correct, especially with Maran eggs. Therefore, I bought a hygrometer, and it seemed to work. I ended up with 9 RIR and 6 French Black Copper Maran chicks. (They are doing very well :-).
This time around, I have done everything the same as I did last time. Same type of eggs and everything. On day 18, I made sure all the channels were full of water, and even added a wet sponge, wrapped in a wet washcloth.
At first, it seemed fine, but then my hygrometer started showing that the humidity was dropping. It dropped to 30 and would not rise. On day 21, I even tried inserting a straw through the openings in the top, and used a dropper to add warm water, just to top off the channels and make sure the sponge/washcloth was wet. Still no change in the hygrometer.
On day 22, I had 1 chick pip, but then died w/out ever getting any further. It is now day 23, and none of the other 23 eggs are doing ANYTHING. According to the hygrometer, the humidity has dropped to 25, but the channels are still full.
I hate to say it, but I think I've killed them all. I'm wondering if the hygrometer is giving off incorrect readings, and it resulted in me drowning the chicks with too much humidity. My thoughts are to give it 1 more day, and then borrow a hygrometer from my inlaws to compare readings with mine.
If it's not the hygrometer, do you have any other ideas?
What am I missing?
Thanks in advance!!!
